邯郸热电厂气力除灰系统存在的问题及改造
摘要
邯郸热电厂气力除灰系统在运行中存在出力不足、堵管、管道磨损、用气量大、落灰不畅等问题
对此
提出了增加仓泵容积、改进气灰混合方式、更换磨损弯头、降低输灰速度及空气系统增容改造等措施
实施后基本解决了上述问题
保证了系统运行的稳定性。
Abstract
The problems existing in operation of pneumatic ash handling system in Handan Thermal Power Plant are as follows:insufficient output capacity
clogging in pipe
worn-out of pipelines
large amout of used air
and inadequate ash-dropping etc..For these
some measures
such as increasing the capacity of depository pump
improving mixing mode of air and ash
replacing the worn-out elbows
decreasing the speed of ash handling
and retrofitting the air system to increase the capacity etc.
have been put forward.After implementation
the above-mentined problems have basically been solved
ensuring the stability in operation of said system.
